Some of these are laid out in the hardest possible valve combinations tuning wise. While, they're correct. There are better alternate combinations. Let's look at B. As I was taught, the B scale (starting 3rd line in staff B) should play as 2, 1&2, 2, 0, 2, 2&3, 1, 2. It is taught this way to add less tubing to produce the same pitch. The higher in the trumpets range, most times, the less tubing you need. Playing top space E with 1&2 is possible but it's usually extremely flat. Try playing E with no valves as a open partial between C and G.

If you doubt me go and strike your tonic on c major on keyboard then sound this c you have been given as your c on trumpet and see the differences try the other ones they are all incorrect go and learn the concert keys That c you are seeing on that chat is b flat if you doubt check your keyboard
